BOLSTER FOR? RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 698,876, dated April 29, 1902. Application tiled October 5, 190 1. 'Serial No. 77,643. (No model.)

To all whom, it jaag/concerns Be it known-that I, CORNELIUS VANDER- BILT, a citizen of the United States, having an office and post-office address at lOO Broadway, borough of Manhattan, city and State of New York, have invented certain new and useful Improvements in Bolsters for Railway-Gars, of which the following is a full and true description, reference being had to the accompanying drawings, showing one embodiment of my improvements.

The object of my present invention is the productionof a railway-car bolsterof great strength and adapted rto be economically manufactured. y

My new-bolster either as a body-bolster or a truck-bolster,

which latter form is illustrated in the drawings and hereinafter specifically described.

In the accompanying drawings I have shown a truck-bolster madeup of assembled channel-beams, &;c., in ordinary rolled or cast commercial forms, the use of which eiects a considerable saving of time and cost as compared with bolsters made of pressed steel or other special metal-work. My improvements may, however, be incorporated in other forms of holsters wholly or partly of metal.

Referring to the said drawings, Figure lj shows a top view of my new bolster. Fig. 2 is a side View thereof, and Fig. 3 is an end view. Fig. 4 is a perspective view -ot a form of spring-seat attached to the bolster. Fig. 5 is a perspective view of a filling piece preferably inserted between the beams of the bolster.

The improved bolster preferably comprises.

may beadapted for usen VO indicates the lower member ofthe truss,

preferablya continuous channel-beam having upwardly-extending ilanges D. 4.As illustrated, the lower member O is narrower than the member A, and its flanges D when the members are assembled in inverted relation closely iit between the flanges B of the upper member at the ends of the truss. This arvrangementof parts is particularly illustrated langesmay be arranged in any other way which permits of their being superimposed and having the iianges of one or both beams and one which contributes great strength and stiffness to the structure and also provides a very compact and strong arrangement, especially when the same is used in combination with the filling-pieces hereinafter described. In the speciiic form illustrated the beam A is bent downwardly in either direction from the points K K to the points of attachment of the side bearings and then bentupwardly, so as to be parallel with Vthe upwardly-,extending ends of the lower beam O. The latter beam is bent upwardly from a point H midway of its length.

At their fitted ends the beams Aand O are secured by rivets 'E or otherwise. Preferably, however, the rivets will pass through in contact `with the web of the other beam, which is an arrangement preferred by me openings in the webs of .the beams, thus lock-`` Y ing lthe beamstogether, while any shifting will be prevented by the contact of the flanges B and D of the beams. In addition the ends are further stiffened and strengthened by the addition of spring-seats R, as hereinafter described.

Thel strength and rigidity of the bolster will be considerably increased by the^insertion of a illing-piece between the beams at the ends where secured together. Oneform of a filling-piece is illustratedin Fig. 5.0i the drawings. It consists or" a tubular body substantially corresponding in exterior shape to the space between the beams A and O where superimposed. The iilling-piece, which may be a casting, is provided with openings E',

through which the rivets E will pass, and withl side openings U for the bolts U, .hereinafter described. Y

It is always desirable in order to impart strength and stiffness to the structure of the bolsters to employ a large number of rivets to secure the different members together, and the preferred arrangement of my bolster, wherein the upper compression member has its fianges downwardly extending and the lower tension member has its flanges upwardly extending, with a filling-piece interposed in the space between them, makes it possible to employ a considerable number of bolts, rivets, or other devices to secure these members together. Thus it will be seen that Ihave shown in the accompanying drawings means for securing these three members together, including bolts T, passing through the anges of both beams and the fillingpiece, and also shorter bolts or rivets E, which pass through the webs of both beams and through the filling-piece. In addition to or as substitutes for the longer bolts T, I may employ rivets or short bolts, which secure each pair of overlapped flanges without eX- tending across the bolster.

The compression member A and the tension member C are spaced apart midway of their length by one or more metallic parts, comprising the king-bolt socket of the truck- Preferably I employ a casting Gof one piece, adapted at its top and bottom to closely fit between the flanges of the beams A and C, as well as to closely fit the angles K K and H of the beams.

Referring to Fig. 2, it will be seen that the casting may be secured to the tension-beam by rivets J, and after vaddition of a center bearing-plate L the casting may be secured to the compression-beam Aby rivets M, which pass through the plate, beam, and casting.

The center bearing-plate is provided with an opening N, which registers with an opening through the compression-beam A, and with a recess or opening in the casting G, the whole completing a socket for the reception of the king-bolt depending from the bodybolster of the car. To the track-bolster made as described I preferably add side bearings O and springseats R. While these may be of any suitable form and may be separate or" integral, I prefer the forms shown in the drawings.y The side bearings O may each be of the usual shape, projecting upwardly from the bolster end and provided with a recess in its upper face for retaining the friction-roller. In order to firmly secure the side bearings to the bolster, I provide rivets P and Q, the latter being sufficiently long to pass through both beams of the bolster, adding to the strength and s'tiness of the structure.

The construction of spring-seat preferred by me is shown in Fig. 4 of the accompanying drawings. It consists of a hollow box-like vst )ring-seat may be a solid block closely fitting at all its parts upon the ends of the bol- 1 ster. Preferably',- however, the spring-seats, as especially shown in Fig. 4, are provided with front and rear flangesVand W, having `inclined edges and adapted when attached to the bolster to closely fit the bottom of the tension-beam. f v l I do not desire to be understood as confining the employment of my invention to the construction illustrated in the drawings and heretofore described. Obviously many modifications thereof 'within the scope of-my claims of theweb will readily suggest themselves to skilled persons.

What I claim isl. A bolster for railway-cars, comprising a truss having an upper compression member with flanges, and a lower tension member with fianges, said members having their flanges placed side by side at the ends of the truss, and there secured together by means which pass through both beams, and filling-pieces at each end of the bolster, in the spaces between the beams.
